在本实施例中，该音量自动控制方法包括以下步骤。
步骤S10，在视频会议终端当前进行视频会议时，实时接收所述视频会议对应的网络发送的预设数量的音频数据；
在本实施例中，视频会议中的终端主要包括会议室型硬件终端、PC软终 端、web RTC(Web Real-Time Communication，网页实时通信)终端和移动设备软终端，这些模块为现有视频会议系统的基本功能模块，本发明中还包括音量设置模块、音量检测模块以及音量调整模块，其中，音量设置模块用来获取预设的音量范围值；音量检测模块用来根据解码后的音频数据，分析得到音频数据对应的音量大小；音量调整模块用来根据接收到音频音量，再与音量设置模块设置的音量范围进行比较，从而自动调整输出音量。
具体地，在视频会议终端当前进行视频会议时，实时接收所述视频会议对应的网络发送的预设数量的音频数据，需要说明的是，视频会议终端支持点对点的会议，还支持多点会议，故发送音频数据的远程终端可以是视频会议终端(点对点会议)，也可以是视频会议的MCU(Multi-point Control Unit，多点控制单元)，本实施例中的音量自动控制方法是实时对通过网络接收到的音频数据进行音量控制。
步骤S20，基于预设音量范围确定所述预设数量的音频数据是否满足预设音量控制条件；
在本实施例中，通过视频会议终端通过音量设置模块获取预设音量范围，然后判断收到的音频数据是否满足预设音量控制条件。
具体地，步骤S20包括以下步骤。
步骤S21，基于所述预设数量的音频数据执行解码操作生成预设数量的PCM码；
在本实施例中，通过视频会议终端的解码模块对接收到的音频数据进行解密操作，其中，解码模块的主要功能是将接收到的音频数据转换成PCM码，用于后续操作及音频播放。视频会议终端一次接收预设数量的音频数据，故解码模块每次对预设数量的音频数据进行解密操作，从而输出预设数量的PCM码。
步骤S22，基于所述预设数量的PCM码确定所述预设数量的音频数据的当前音量；
在本实施例中，通过视频会议终端的音量检测模块进一步对PCM码进行处理，根据预设的算法对PCM码进行计算，从而得到当前音量。
具体地，步骤S22包括以下步骤。
步骤a，将所述预设数量的PCM码分别求绝对值并求均值，得到平均能量；
步骤b，基于所述平均能量确定所述当前音量。
在本实施例中，将预设数量的PCM码先进行求绝对值，然后将全部求绝对值后的PCM求和，接下来再求平均值得到平均能量，将平均能量做进一步的量化处理，最终得到通过预设数量的音频数据对应的当前音量。
举例说明，PCM码采用16位数据来表示，预设数量为N，求绝对值后的PCM码数组data[N-1]，对PCM码求和，得到SUM＝data[0]+data[0]+....+data[N-1]；接下来计算该段数据的平均值，得到平均能量VALUE＝SUM/N；最后对平均能量做进一步的量化处理，得到当前音量。因为PCM码采用16进制，音量值需要是1～100之间的数，故当前音量VOLUME＝VALUE*100/32767。
步骤S23，确定所述当前音量是否在所述预设音量范围内，其中，当所述当前音量不在所述预设音量范围内时，确定所述预设数量的音频数据满足预设音量控制条件。
在本实施例中，通过视频会议终端的音量检测模块得到音频数据的当前音量后，进一步对当前音量进行判断，判断方法为：将当前音量与预设音量范围进行比较，如果当前音量在预设的音量范围内，则确定音频数据不满足预设音量控制条件，如果当前音量不在预设的音量范围内，则确定音频数据满足预设音量控制条件。
步骤S30，当所述预设数量的音频数据满足预设音量控制条件时，基于预设算法调节所述预设数量的音频数据的音量。
在本实施例中，如果音频数据不满足预设音量控制条件，则无需对音频 数据音量进行调节，如果所音频数据满足预设音量控制条件，则基于预设算法调节预设数量的音频数据的音量。
具体地，步骤S30包括以下步骤。
步骤S31，当所述预设数量的音频数据满足预设音量控制条件时，获取预设音量值，基于所述预设音量值以及所述当前音量确定音量调节系数；
步骤S32，基于所述音量调节系数调节所述预设数量的音频数据的音量。
在本实施例中，预设音量值在预设音量范围内，用户可以根据具体情况设置，预设值可以是预设音量范围的中间音量，也可以是预设音量范围的下限音量或上限音量，本发明对预设音量不做限制，请根据实际情况确定。具体地，视频会议终端获取到预设音量值后，根据预设音量值和当前音量计算音量调节系数，音频调节系数等于预设音量值与当前音量的比值。在一实施例中，将每个PCM码都乘以音量调节系数，得到调整音量后的PCM码，也就是调整音量后的音频数据，由于音量调节系数可能是大于1的数，故需要对超出PCM码边界值的数据进行修正，使修正后的PCM码在PCM码对应的边界范围内。
举例说明，预设音量为A1，当前音量为A2，PCM码表示为DATA[i]，计算得到音量调节系数K＝A1/A2，将PCM码乘以K，得到调整音量后的PCM码，也就是调整音量后的音频数据为：DATA[i]＝DATA[i]*K。
本实施例提出的音量自动控制方法，在视频会议终端当前进行视频会议时，实时接收所述视频会议对应的网络发送的预设数量的音频数据，而后基于预设音量范围确定所述预设数量的音频数据是否满足预设音量控制条件，接下来当所述预设数量的音频数据满足预设音量控制条件时，基于预设算法调节所述预设数量的音频数据的音量。通过检测当前实时接收的音频数据的当前音量判断音量过大或过小的可能性，基于预设算法实现了对本地会议终端音量的自动调节，解决了现有视频会议终端在和不同会场通讯时，由于声音大小不一致需要不断调整本地终端音量的问题，同时提升了用户体验。
基于第一实施例，提出本发明音量自动控制方法的第二实施例，在本实施例中，步骤S20之后，还包括以下步骤。
步骤S40，当所述预设数量的音频数据满足预设音量控制条件时，基于所述预设音量范围以及所述当前音量确定音频输入增益系数；
在本实施例中，通过视频会议终端通过音量设置模块获取预设音量范围，通过音量检测模块确定当前音量，然后判断当前音量是否在预设音量范围内进而判断音频数据是否满足预设音量控制条件。
具体地，当预设数量的音频数据满足预设音量控制条件时，根据预设音量范围以及当前音量确定音频输入增益系数，该音频输入增益系数用于远程会议终端调整其音频输入增益，当远程会议终端的音频输入增益调节到一个合理范围时，则本地视频会议终端接收到的音频数据的音量也在预设音量范围内。
步骤S50，发送包括所述音频输入增益系数的调节指令至远程会议终端，以使所述远程会议终端调节远程会议终端对应的音频输入增益。
在本实施例中，当根据预设音量范围以及当前音量确定音频输入增益系数后，本地视频会议终端发送包括音频输入增益系数的调节指令至远程会议终端，以使远程会议终端调节远程会议终端对应的音频输入增益。
在一实施例中，步骤S20之后还包括以下步骤。
步骤S60，当所述预设数量的音频数据满足预设音量控制条件时，基于所述预设音量范围以及所述当前音量确定音频输出音量系数；
在本实施例中，通过视频会议终端通过音量设置模块获取预设音量范围，通过音量检测模块确定当前音量，然后判断当前音量是否在预设音量范围内进而判断音频数据是否满足预设音量控制条件。
具体地，当预设数量的音频数据满足预设音量控制条件时，根据预设音量范围以及当前音量确定音频输出音量系数，该音频输出音量系数用于远程会议终端调整其音频输出音量，当远程会议终端的音频输出音量调节到一个 合理范围，则本地视频会议终端接收到的音频数据的音量也在预设音量范围内。
步骤S70，发送包括所述音频输出音量系数的调节指令至远程会议终端，以使所述远程会议终端调节远程会议终端对应的音频输出音量。
在本实施例中，当根据预设音量范围以及当前音量确定音频输出音量系数后，本地视频会议终端发送包括音频输出音量系数的调节指令至远程会议终端，以使远程会议终端调节远程会议终端对应的音频输出音量。
本实施例提出的音量自动控制方法，当所述预设数量的音频数据满足预设音量控制条件时，基于所述预设音量范围以及所述当前音量确定音频输入增益系数，而后发送包括所述音频输入增益系数的调节指令至远程会议终端，以使所述远程会议终端调节远程会议终端对应的音频输入增益。通过检测当前实时接收的音频数据的当前音量判断音量过大或过小的可能性，进而通知远程会议终端调节其音频输入增益，实现了对本地会议终端音量的自动调节。
基于第二实施例，提出本发明音量自动控制方法的第三实施例，在本实施例中，所述音量自动控制方法包括以下步骤。
步骤S80，在视频会议终端当前进行视频会议时，实时接收来播放器播放的回声数据；
步骤S90，确定所述回声数据对应的回声音量是否在预设回声范围内；
步骤S100，当所述回声音量不在预设回声范围内时，基于所述回声数据调节所述视频会议终端的音量。
在本实施例中，在视频会议终端当前进行视频会议时，实时接收来自播放器播放的回声数据，其中，回声数据是指与视频会议终端连接的电视机或音响等播放设备里发出来的声音。
在一实施例中，视频会议终端在回声抵消之前，通过音量检测模块检测回声的当前音量并和预先设置的回声范围做对比，如果回声的当前音量在回声范围内，则不需要调节视频会议终端的音量，如果回声的当前音量不在回 声范围内，则需要调节视频会议终端的音量。当回声音量不在预设回声范围内时，可以根据预设的音量调节算法调节视频会议终端的音量，从而实现音量的自动调节，其中预设的音量调节算法为现有算法，根据实际情况确定。
